Vaccine holds promise for hay fever sufferers

Baltimore  Could the sneezy, runny-eyed misery of hay fever one day be a thing of the past? Scientists are reporting encouraging results from early tests of a vaccine they hope will give long-lasting relief from this seasonal scourge.

The experimental vaccine has been tested on only a couple of dozen people so far, but it substantially relieved symptoms for those who received it in six weekly shots, and the benefit lasted for at least two years, doctors reported in today's New England Journal of Medicine.
